“The Suicide Squad” doesn’t exactly have a shortage of unlovable characters. There’s a giant kaiju starfish with mind control powers, two separate and equally unlovable fascist political regimes, and John Cena and his uncompromising willingness to do whatever it takes to preserve liberty no matter what he has to eat a beachfull of to get it done.
Towards the top of the list of the film’s most difficult people is the Thinker, the super scientist with a penchant for scalp modification and a love of body horror human experimentation. Some folks might recognize the mad filling out the Thinker’s spectacular tracksuit by his familiar ability to curse with the cadence of a rageful poet. Others might have noticed that his sci-fi condescension has the practiced tone of someone that’s shouted at a companion from across a TARDIS console.
The Thinker, AKA Gaius Grieves, is played in the film by Peter Capaldi. If you don’t know the name, you should. If you do know the name, get ready to know it even more.
